Hi, I'm having a problem with one of my hens 1. She is a 2.5 year Buff Orpington hen. I haven't noticed a weight change yet. 2. She is normally bright, social, and alert but has been acting very slow, not talking much, less desire to eat, Just stands around sometimes. She is eating, but she is not as enthusiastic to eat and might not be eating as much. 3. She has shown symptoms for 3 days now. 4. No other birds are showing symptoms. 5. No trauma, broken bones, bleeding, etc. 6. She has had coccidiosis in the past, might have exposed her to something? 7. She has been eating her feed, some treats (worms, seeds, cucumber, corn bread etc), and drinking water. 8. I've been finding very white, watery poops with a tiny bit of green matter in them. Although I have not seen her drop them, the other hens have been having normal poop/don't do this so I'm pretty sure they are hers. 9. I have not yet treated yet but may put corrid in the water tomorrow as a preventative. 10. I would like to treat her myself, but will go to the vet or send a stool sample if needed. 11. I do not have a picture of the poop at this time but can try to get one tomorrow. 12. She lives in a 9-12 bird coop with one other standard, and 4 bantam hens, has a run, and free ranges weather permitting and when I am home. I use pine shavings in the coop and hay in the nest boxes. I'm not sure if this could be cocci again. (No blood in poop). I read something about a bacteria called clostridium perfringens. Her poop and symptoms seem to match the description, plus it says hens who have had cocci are more likely to get this, which she has. I know my hens love to drink dirty, stagnant water left over from rain storms. Could they get something from that? Should I treat for cocci just in case? My birds have never been wormed before. Any advice appreciated.
